Masticating juicers are superior in pretty much every respect to centrifugal juicers, but you can expect to pay more for them. They work by "chewing" the food before they filter out the juice.
Their method of juicing makes them far more efficient than centrifugal juicers. It also means that they can operate at lower speeds, making them quieter. The juice obtained with masticating juicers is better quality too, with more nutrients in it, plus you can keep the juice for longer, refrigerating it for up to 72 hours.
Another important difference is that masticating juicers are also much more versatile than centrifugal ones in terms of the foods that you can juice. Whereas centrifugal juicers are only efficient at juicing fruit and vegetables, masticating juicers can be used with wheatgrass and herbs and for making baby food, sorbets and nut butters.
